So you have just received your mesh band or one of our watches equipped with a stainless steel mesh band but the size does not fit your wrist yet.
Here is the way to adjust it.
Use an horologycal strap tool or a small screwdriver like the ones used to adjust eyeglasses.
Gently slide it under the rotating adjustment plate and lift up.
Then you can slide the clasp up and down the mash band until the proper fit has been obtained.
When the proper fit for your wrist has been obtained, just press the plate firmly downward with your hand and engage the tip of the adjustment plate with one of these slots for a reliable and secure fit.
